at one point, president obama said nelson mandela makes me want to be a better man. you mentioned raul castro, of course, with nearly 100 world leaders gathered at this event, there were bound to be surprises. raul castro was on the diaz and speaking, as well as president obama. it would have been sort the of impolite. it would have been kind of a slap, really, if the president had gone up on stage and not greeted the cuban leader. that's par for the course at these types of events. as you also know, carol, he embraced president russov of brazil, a country that has been steamed at the united states because of those surveillance issues. he is headed away from the stadium and headed back to a rendezvous point before heading back to the united states. carol? >> going back to that handshake, maybe scottie can put it back up on the screen, the handshake between president obama and raul castro. quote, we have to reject the policies we put into place in 1961. in other words, it's time to end the nation's cold war standoff with cuba. i know what you said about this handshake
